To all whomit may concern: r

lie it known that l, BUTLER J. HAsKrNs,

a citizen'of the UnitedStatearesiding at;

lilansas Gity, in the county of Jackson and it'll State of Missouri,haveinvented certain new and useful Improvements in Electrical BlockTrain titoppage and Signal-Setting Systems,

otwhich the following is afspecific atlon.

This invention relates to electrical block train stoppage and signalsetting systems,

and the object is to produce a closed circuit system whereby theelectrical connection of the rail members 011 the block by the entranceoil? a train into such block or the breaking of a rail, shall, inaddition to settingithe'semaphores protecting such block, as common,

tectedby housings 16 and 17, and the former is equipped with an inclinedguard 18 at the end from which the approach of a train T occurs, inorder that any loose part dependinglow enough to strike the coil, mayona counter the guard and be deflected upwardly thereby. From theforegoing taken in connection with the drawing, it will be apparent thatwhena train leaves one block and enters another, it shunts the trackcircuit (through i the Wheels and axle) from thesolenoid in the blockjust passed to ermit the core 9 of said solenoid to drop and therebybreak the connection between conductors and 11;

i and thusleave the coils 14 and of the said unoccupied or passed blocksusceptible to energization m. a manner hereinafter ex- Mounted uponeach train is the following equipment; 19 and 20 are coils, the formernormally energized, supported beneath the engine in such position thatthey shall pass over coils 14: and 15, so that the magnetic field ofcoil 19 shall inclose coil 14: at the moment coil 20 is above coil 15.If at this time the block ahead is not occupied by a train nor the railsof said block otherwise electrically connected, or a rail displaced orbroken, the coil 14 will be unafl'ected because the solenoidof the sameblock'is energized and the core" thereof consequently engaged with theadjacent contacts 10 and 11. On the other hand, if the rails of theblock ahead are connected by a train or otherwise,

and areintacuthe circuit between coils 14 and .15 isnot shorted, hencethe proximity ofrcoil -19 to coil 14 produces an induced currentPthroughcoils 14 and 15, the energization of the latter energizing the coil20-atj the time just above coil l5.--for a a purpose hereinafterexplained. Magnets 19 and 20 are preferablyprovided with housings 21 and22 corresponding to housings 16 i and 17 if desired, and housing 22 isequipped with an upwardly and forwardly inclined guard 23 to perform thesame function for coil 20 as the guard 18 performs for coil 14.

,oil 19 is connected by a conductor 24: to a dynamo 25 on the engine,and the latter is connected by, a conductor 26 through a magnet 27 andconductor 28, to a movable contact or lever 29 held normally by aretractile spring 30 against a contact 31, connected by i conductor 32to the coil 19 This circui't is normally closed so that 0011 27 may holdthe armature 33 attracted,.said armature be- I ing mounted upon a lever34 for holdin aweighted'arm 35 in elevated posltlon.

weighted arm is to operate a valve 36v of any suitable type controllingthe air brake line 3710f the train, and to release said arm toconnected'to lever 34? to trip the same from 'theweighted arm when thecircuit l: the dynamo is broken. v a

i is ajmagnet 39 electricallyconnected by con-' i. :duc'tors il-and 42'tothe coil 20. Fromthe' ,foregoing,'it will be seen that when one-.efiect the o eration of thebrakes, (not shown),-of't e train,retractile spring 38 is through Arranged adjacent movablecontact orlever 29 and an armature 40 carried thereby,

block isoccupied by'a train-and therefore efi'ects a'break in thecircuit through 7 the ,solenoid' 6 in the block to the rear of the.bccupied block, the short circuit through coil 14' established by.conductors 1O and-11- 'and core 9 is broken, assuming that a train isblock B, it. will be seen-that when the coils 19Y2Iidf20offa' train-inblock A are respectively in superposed relation [with coils14 and 15, a:currentwill be induced coil 19', through coils 14 and 15, and bythelatter a; current will be induced through- .coil 20, conductors tland42, and electrotween lever29 and contact 31.

' It" will be-apparent'that the shunting of ;:a solenoid out of circuitin one block may, 'as'he'reinbefore suggested, occur through the fall ofa bridge, the displacement of a rail or the connection of the rails by awire in the next block-ahead.

From, the above description it will. be

' understood that the embodiment of the invention may be in variousforms as regards its form, detail construction and organiza- ,tion ofparts, without departurefrom the principle of construction shown orthe'scope oi the appended claims.
